If there is a barycenter to the whole universe, it would have to be static. That is kind of the definition of barycenter, the center of mass. If the center of all the mass in the universe were moving, what is it moving past? Something outside the universe? What would that even mean?

Well, there is no center to the Universe.
In particular, it has no baricenter, which refers to the center-of-mass of a system of orbiting bodies.
On the other hand, nothing is really static in the Universe---everything is moving in the overall gravitational field of everthing else.
It is thought that "Mach's Principle" may provide a reference frame that is non-rotating---the average position of everything defines the standard of rest.
